How Installing Energy-Efficient Windows in Alpharetta Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Alpharetta

Each window installer offers various services and has different prices depending on several factors.

How Much Do New Windows Cost?

On average, Alpharetta homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. How much it will cost varies depending on several factors, including size, the location of your home, type, number of windows, material and more.

It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Alpharetta homeowners $362+ a year when replacing single-pane windows.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In regard to window installations, in general there are two types that your installer will have: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Alpharetta, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.
